This invention relates to improvements in cleamngdev ces for pipecondults particularly thecleaning of beer pipe lines, and it is theprincipal object of our invention to provide a device of this type inwhich the cleaning beads are collected in the conduit to form a compactbody of a length proportionate to the length of the pipe conduit, and assuch-- returned into the bead reservoir so that all loss of cleaningbeads is efi'ectively avoided,

while the waste water is discharged In the known devices of this kindthe cleaning beads are distributed singly in the pipe line and areprevented by the necessarily constant operation of the four-way cock toeffect a cleaning under full pressure to return as a body into theirreservoir resulting in a loss of beads and the undesirable presence ofstray beads within the line.

It is the object of our invention to overcome this disadvantage andtherefore another object of our invention is the provision of aplurality of damper-and throttle' lates within the pipe line to collectthe bea s for their return in one body to the bead reservoir.

A further object of our invention is the provision of a bead-pipe linecleaning device in which the damper plates are provided with a pluralityof openings allowing the passage of the cleaning fluid and 'dirt orresidue while retaining the beads.

' A still further object of our invention is the provision of abead-linecleaning device of' comparatively simple and thereforeinexpensive construction, yet durable and highly efficient in operation.

These and other objects and advantages of our invention will become morefully known as the description thereof proceeds and will then bespecifically defined in the 'ap-.

pended claim. 4 i

In the acompanying drawing forminga material part of this disclosure:

Figs. 3, 4, 5, and 6, are. sectional views on line 33 of Figure 2,illustrating the various positions of the four-Way cock. I

Fig. 7 is a sectional elevation of a modified form of a four-way valveand illustrating the arrangement of a sieve.

As' illustrated, the cleansing water passes through pipe 10, adapted'tobe attached to a source ofwater into an injector 11 of standardconstruction. A reservoir 12 adapted to contain the cleaning beads isconnected by means of a conduit 13 controlled by a valve 14 with themixing chamber 15 into which the beads are drawn to be injected by theinj ector into the pipe 16 connected by the fourwaycock 17 with the pipelines 18, 18, leadmg to the conduit to be cleaned.

A pipe conduit 19 .conducts the beads back into the head 20 ofreservoirl2, which is equipped with an annular inspection 0 eningcovered by a glass plate 21 held in'p ace by means of plates 22, 23,held together by headed bolts 24 and their nuts 25, while the wastewater is removed through pipe 26 A cleaner nipple 27 controlled by, avalve 28 is provid: d near the bottom of"reservoir 1 2, and the injectorcan be regulated by means of a valve 29.

The valve body 30 of the four way cock is adapted to be operated bymeans-of a handle 31.

According to our invention a number of damper or throttle plates 32 inthe body 30 of the valve and moving therewith are interposed in thepipeline at the four-way cock connection with the body thereof which atcertain times as will be hereafter Indie fully described close one orthe other of the pipes in order to allow a collection of the beads inthe pipe line as a compact body for their return into the reservoir 12as for instance indicated at 33 in Figure 1 within pipe 18.

In Figure 7, we have shown the customary form of our damper plate 32,provided with a plurality of" openings 34 for a purpose hereafter morefullyv to be described.

The device operates as follows:

returned after their passage through said pipe line through pipe 18.They arrive at the second damper plate 32' which is in a positionclosing conduit 18 so that the beads must collect therein as a compactbody as indicated at 33 in Figure 1, while the water flows throughopenings 31 in the damper plate into conduit 19 leaving-through pipe 26and hose attached thereto.

If now the four-way cock body 30, to which the dampers are connected isturned into the position indicated in Figure 4 in which the water uponclosure of cock 14 rushing through the injector and pipe 16 will passthrough damper plate 32 into pipe line 18 circulating the body of beads33 through the bead pipe line into pipe 18, the damper 32 of which isclosed to stop the beads while allowing the water to flow off throughpipe 19. If now the four-way-cock is turned to assume the positionillustrated in Figure 5,

the water will enter pipe 16 and through damper 32 into pipe 18 to drivethe body of beads in said line into the beer pipe line to circulatetherethrough and return the body of heads into line 18 the damper 32 ofwhich being closed will stop the beads while the water can flow ofithrough the openings in saidplate into pipe line 19.

If now the valve body 30 is turned by means of its handle 31 into theposition shown in Figure 6, the water rushing through pipe 16 will drivethe body of beads collected in pipe 18 to circulate again through thebeer pipe line and then return through pipe 18', the damper 32 of whichis open so that said body of beads can return into reservoir 12, whilethe water is drawn ofi at 26.

It will be clear that the damper plates 32, 32', can be steered by anysuitable mechanical means or may be so connected to the valve body toassume their proper positions corresponding to the various turningmovements of the valve body, and that upon closure of cock 14 while thebeads are collected in reservoir 12 as aforedescribed a cleaning of thebeer conduit with glean water can be etfected in alternate directionsaccording to the various positions of the four-way cock.

If desired a receptacle 35 containing a cleaning chemical may beconnected with the injector.

It willbe understood that we have described and shown the preferred formof our device only and that we may make such changes therein, and in theconstruction of the minor details thereof as come within the scopev ofthe appended claim without departure from the spirit of our inventionand the principles involved.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is:

In an apparatus of the classdescribed, a pipe line, a reservoir for thecleaning bea s,

an injector, a water supply for said injecto voir, and means fordischarging the waste water and residue of the cleaning process.
